Analysis

The flight instructor reported that, the student pilot was making the landing to the 1,975 ft gravel runway and landed about midpoint. The flight instructor came on the flight controls and applied brakes, but the airplane’s left wing impacted terrain and vegetation before the airplane came to rest, about 100 ft beyond the departure end of the runway. The airplane sustained substantial damage to the left wing and wing root. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
